Montreal 1989, does it remeber anything to you?
Back in that year “Perhaps the single most successful international agreement to date” (Kofi Annan, former Secretary General of the United Nations) was signed.
Today 27 years later its effects are visible to everyone.
The Protocol (for who does not remeber) banned the use of CFC, chlorofluorocarbons, and other ozone-depleting substances (ODS), to help the ozone layer to restore itsself.
Recently, a MIT study confirmed that the ozone hole is shrinking. The size of the ozone hole above Antarctica each September has shrunk from about 20m square kilometres to 16m square kilometres since 2000.
It is now clear that banning CFCs through the Montreal Protocol almost 30 years ago was the right decision. The ozone hole is starting to recover, perhaps to close completely by the 2050s.
This confirm the theory that if we act altogether we can achieve great results. Is cooperation the answer to the man-made climate change problem? Defintely YES!
The successes and lessons of the Montreal Protocol are instructive in the context of global climate change discussions. Clearly, a multilateral agreement with strong, science-based and legally binding limits is what we need.
If we act collectively we can do and achieve more!
Remeber togheter we stand divided we fall!
